MKV to M4V Question

I have some MKV files that are x264 video, and DTS audio. I want to re-mux them to M4V to stream to my ATV3. Only remux video though, as I don't want to re-encode and lose more quality.

Currently I've been using MP4Tools for the remux since I need to convert the DTS audio to AC3 DD 5.1. I then use Subler to import all the meta information and clean the file up for iTunes.

I'd like to find 1 program to do it all for me in 1 sweep if possible. As I understand it, Subler can't do DTS to AC3 DD 5.1, so I need to use MP4Tools for that, but MP4Tools doesn't have any of the meta import features.

I tried using iFlicks, but I can't seem to force it to not transcode, and just remux. Every time it spits out a file almost half the size of original, and always says Encoding H.264 in the process. Is there anyway to force iFlicks to just remux, don't touch video, and make the DTS to AC3?

I haven't tried iVI since I would like a trial before I purchase an app.

Monitors a specific folder, grabs the file, converts it to MP4 then dumps it into your itunes media folder and deletes the original file. Very easy to use and is very customizable.

second that. I have converted hundreds of TV shows from MKV to M4V. Most MKVs fit the AppleTV standard and take less than a minute to lose the MKV wrapper and put on the M4V wrapper. NO Transcoding. However it will transcode if you want to convert 1080p to 720p or if the MKV format does not meet Apple TV spec.

I'd also recommend Subler. It'll remux without a re-encode, let you incorporate chapters, and is integrated with themoviedb.org to easily grab meta-data, etc., and it even includes some extended meta-data for things like ratings, etc.
